UM-Bot Posted October 19, 2016 #1 Share Posted October 19, 2016 The ExoMars mission's lander Schiaparelli has reached Mars but it is unclear whether or not it survived. http://www.unexplained-mysteries.com/news/299955/fate-of-exomars-lander-hangs-in-the-balance 3 Link to comment Share on other sites More sharing options...
paperdyer Posted October 19, 2016 #2 Share Posted October 19, 2016 I wonder if the ESA knows about where their probe ended up and whether our current Rover is near enough to check on the ESA probe, It would be a shame if the probe crashed or impaled itself on something on landing. 1 Link to comment Share on other sites More sharing options...

Merc14 Posted October 19, 2016 #4 Share Posted October 19, 2016 Too bad, it would've been nice if their landing system worked. Hopefully the telemetry they did get will show them the problem so they can correct it for their rover 1 Link to comment Share on other sites More sharing options...

Yes, NASA is the only agency that has had success to date but it is a very challenging environment and NASA's success has come through the loss of several of their own spacecraft at the red planet. Lessons learned the hard way but ESA's plan, in my amateur mind, looked sound and hopefully the failure was not an indictment of their basic landing design. The more the merrier, in my mind, and a brand new communications platform helps everyone conquer the new world we are exploring. 1 Link to comment Share on other sites More sharing options...

seeder Posted October 20, 2016 #8 Share Posted October 20, 2016 UPDATE: Not looking good folks Quote Schiaparelli Mars probe's parachute 'jettisoned too early' Europe's Schiaparelli lander did not behave as expected as it headed down to the surface of Mars on Wednesday. Telemetry data recovered from the probe during its descent indicates that its parachute was jettisoned too early. The rockets it was supposed to use to bring itself to a standstill just above the ground also appeared to fire for too short a time. The European Space Agency (Esa) has not yet conceded that the lander crashed but the mood is not positive. Experts will continue to analyse the data and they may also try to call out to Schiaparelli in the blind hope that it is actually sitting on the Red Planet intact. In addition, the Americans will use one of their satellites at Mars to image the targeted landing zone to see if they can detect any hardware. Although, this is a slim hope because the probe is quite small. http://www.bbc.co.uk/news/science-environment-37715202 Link to comment Share on other sites More sharing options...

Derek Willis Posted October 20, 2016 #14 Share Posted October 20, 2016 I am sure the ESA ExoMars team won't be too disheartened because the orbiter seems to be working fine. The main purpose of the orbiter - the Trace Gas Orbiter - is to look for and analyse gasses in Mars' atmosphere that may indicate signs of life, e.g. methane. To cheer up the team, here is about the worst pun you will ever hear - is the science of analyzing gasses on an astronomical body known as gastronomy? 2 Link to comment Share on other sites More sharing options...
Merc14 Posted October 20, 2016 #15 Share Posted October 20, 2016 Schiaparelli was mainly there to test their proposed lander technology so if the telemetry data can tell them what went wrong then it will have accomplished much of its mission. The lander only had a few, very basic, instruments on it that were to run on battery power for just a few hours (8 or so) so no real loss to the main science mission. Originally it was supposed to carry an expensive science package but that was scaled way back due to cost overruns and in hindsight that was a good decision as the landing was ultimately unsuccessful although it seemed to do a good job getting the package down to very near the surface. 3 Link to comment Share on other sites More sharing options...

It was a pity the landing failed, because a success - even if the lander was relatively basic - would have been a symbolic triumph after the failure of the ESA lander Beagle II in 2003. Any failure of a lander shows how difficult landing is on Mars is - something the proponents of "low cost" manned flights to Mars (i.e. Mars One) ought to be more open about when they make exaggerated claims of how safe this will be. I know Elon Musk is keen to send people to Mars, but I still think it will be the vastly experienced NASA who will carry out the first manned missions (hopefully in my lifetime!).

Doc Socks Junior Posted October 20, 2016 #17 Share Posted October 20, 2016 It got the package all the way down quicker than scheduled and put more objects on the surface than initially planned for! Seems like a big win to me. Link to comment Share on other sites More sharing options...

Seems like a big win to me. Hur hurr. Sad but seemingly true. Parachute deploys early, is destroyed. Descent velocity is much higher than planned, boosters fire at planned altitude and fire for a much shorter time because the lander is obliterated as it touches Martian earth. 1 Link to comment Share on other sites More sharing options...

Merc14 Posted October 21, 2016 #20 Share Posted October 21, 2016 Telemetry is telling ESA that the parachute was jettisoned too early and the rockets fired for too short a time. http://www.bbc.com/news/science-environment-37707776 It was a technology demonstrator and provided valuable data for the next landing attempt, a rover if funding is secured, so not a total loss from an engineering perspective I guess but a clean landing is always preferred obviously..

Hopefully, with a manned mission the avionics will carry the same Warnings, Cautions, and Advisories to the flight crew that atmospheric aircraft have on earth - allowing human interventions to prevent premature parachute separation and / or insufficient retro-rocket thrust duration. These safety interlocks are fairly basic and simple to implement. I also have the sneaky suspicion that the Chinese just might beat ESA and NASA to a manned landing...

Why do you think the Chinese can get there before ESA or NASA when they haven't even got a spacecraft in orbit around Mars much less landed one on the planet? They seem more interested in lunar exploration than planetary exploration right now. Edited October 21, 2016 by Merc14 Link to comment Share on other sites More sharing options...
keithisco Posted October 21, 2016 #23 Share Posted October 21, 2016 Considering that India has a Mars orbiter, and China is pushing ahead with its "2020 Chinese Mars Mission" with the intention of performing a "Sample Return" mission in the 2030´s then I believe they just might steal a march on the west.

Did I say that? NO... I simply stated that China MIGHT get there first. After all they don't have to rely on Congress approving, or otherwise, funds for any mission they wish to plan. NASA and ESA both have to get past all the pork on Capitol Hill and Brussels. Link to comment Share on other sites More sharing options...
